IMPROVED HoRsEsl-los."

Specification forming part of .Letters Patent No. 40,2! 5, dated October 6, 1863.

To a/ZZ whom it may concern,.-

Be it known that I, EMANUEL J. PLEYEL, ofthe county of Dallas and State of Iowa, have invented new and useful Improvements in Horseshoes; andI do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specifieation.

The nature of my invention consists in the shape and construction of six-sided calks with their double-shouldered screws.

'Io enable others skilled in the art to make and use my invention, I describe its construction as follows:

Figure l represents the horseshoe; Fig. 2, a side view of the horseshoe, Fig. 3, the movable toe-piece; Fig. 4, the movable six-sided and pointed calk; Fig. 6, a top View of Fig. 4; Fig, 6, the movable Hat-headed and siX- sided calk.

A represents the ordinary grooves in the horseshoe, in which are apertures B, for the purpose of fastening the shoe to a horses foot by nails, as usual.

C represents the front part or toe of shoe,

raised about one-fourth of an inch and flat at lower shoulder, II, to the face of the sl1oe,to assist in maintaining th'e permanency of the toepiece D. rIhe shoe has its aperture J and female screw to correspond with the screw E, being countersunk at top of the female screw, and straightbelow the screw, as shown in dotted lines at Fig. 2. The toe-piece D, as shown at Fig. l, is iiatter and blunter at the point for summer use than the sharper-edged toe-piece D, as shown at Fig. 3, for wint-er use, and they are also fastened to the shoe by side screws, K, to brace the main screw E and prevent any possibility of its loosening.

L, at Fig. 6, represents the flat six-sided calk for summer use, with its similar screw, E, which is screwed firmly into the heel M of the "shoe, into its corresponding aperture J and female screw.

N, Fig. 4, represents the pointed six-sided calk for winter use, having its like screw E. which is also screwed firmly into the heel M of the shoe, into its corresponding apertures, J, and female screw.

The advantages are the changing of the toe pieces and calks in the most expeditious inanner according to the roads in pleasant or icy i weather, and maintaining their permanent positions in the shoe by the double-shouldered screws.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-
